Methods for creating optical carriers for long-term storage have been analyzed. It is shown that the problem of long-term storage of strategic information can be solved using sapphire discs with microrelief representation of the data. The data are presented on recording submicron structures on the surface of the sapphire substrate and reproducing the recorded data by a focused laser beam.
